This PR frees some esp8266 RAM consumed by the .rodata segment. This can be examined with objdump -s -j .rodata out/Esp8266/debug/build/app_0.out

Store http-parser method strings in flash

Also remove unused http_status_str() function, consumes RAM even though it's never called.
Saves 1100 bytes RAM.

More http-parser strings into flash

No need for these to be in RAM.

Update http-parser lib to final version

Put WS parser error strings in flash

Remove EspDigitalPin

Only MUX addresses are required, and that only needs 1 byte.
Saves up to 196 byte RAM.

Optimise rapidxml lookup tables

Saves 2020 bytes RAM

Add python script to scan/compare CI build logs

Savings:
